IMPROVEMENT IN CHURN-IVIOTORS.

Specification forming part of Letters Patent No 210,580, dated December3, 1878; application filed May 25, 1878.

To all whom it may concern:

Be it known that I, HARDAWAY AMBROSE TURNER, of the county ofBedford andState of Virginia, have invented a new and valuable Improvement inChurn-Motors; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a top view of myimproved churn-motor. Fig. 2 is a longitudinal vertical section thereof,and Fig. 3 shows detail views of the fly.

This invention has relation to improvements in wheel-train motors forchurns.

The object of the invention is to provide means whereby the speed of thestroke of the dash-rod may be regulated at pleasure without using brakesor other like devices, which by their friction tend materially to wearout the journals of the train-wheels.

The nature of the invention consists in the combination, with a churnand its actuating clock-train, of the fly having blades, andextension-win gs having guideways upon their lateral edges, formed byturning the edges of the said wings upward and over, and adapted toreceive the fly-blades and the adj usti n gscrews, as will behereinafter described.

In the annexed drawings, the letter A designates a casing, containing atrain of wheels, B, actuated by a spring in the barrel 0. Upon the axleof the last wheel of the train is keyed a crank-wheel, D, having awrist-pin, a, to which is attached one end of a pitman, J, the other endof which is secured pivotally to the power end of a vertically-vibratinglever, K, having its fulcrum in a hanger, b, depending from the casing.This latter is raised upon legs 0, and the churn L is placed under itdirectly beneath the weight end of the lever K. The dash-rod is pivotedto the power end of said lever, which latter is guided and preventedfrom wabbling by means of a forked metallic guide, G, depending from thecase rapid, according to the quantity of cream in thechurn and othercircumstances.

This speed-adj ustment is attained as follows: The blades 0 of the fly Lare each provided with an extension, d, having on its lateral edges ways1', between which the said blades 0 are snugly received. The wings dslide eudwise toward or from the axis of the fly, thereby lessening orincreasing the beating-surface of the blades, and consequently lesseningor increasing the speed of the stroke of the dashrod. The wings d areadjusted to the blades by means of a set-screw, s.

I am aware that extensible fan-win gs lapped upon each other, andsecured to the crankshaft of a churn power driving mechanism by means ofslots and clamp-screws, is not new, and I make no claim to such devices.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with a churn and its actuating clock-train, of the flyL, having blades 0, the extension-wings d, having guideways 6 upon theirlateral edges, formed by turning the edges of the said wings upward andover, and adapted to receive the fly-blades c, and the adjusting-screwss, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

H. A. TURNER.
